WhatsApp has added a couple of new features, to its Android app’s beta version. The new features are visible on the dialer screen, and only available if the call has been missed or declined by the person you are calling.
Firstly, there is a send “Voice Message” option, which lets you leave a recorded message for the recipient. This is the same as the record and message option available in the chat screen.
The second option is, “Callback”, which lets you ring back the caller, instead of going to the Calls tab. These new features come after the recently introduced “Reply to messages” option, which allows you to reply (quote) to a message in your chat.
You can download WhatsApp Messenger 2.16.194 beta from Google Play (if you are in the beta test program) or get the app from APK Mirror and sideload it to test the features on your phone.
